Creamy Chicken Chili - A skinny variation

CREAMY CHICKEN CHILI

1 lb chicken breast, diced (Even faster used canned chicken)
1/2 medium onion, chopped
1 1/2 tsp garlic powder
1 Tbsp oil
2 cans great northern beans
1 can chicken broth
1 4oz can green chiles (I use two because we like things spicy. :))
1 tsp salt
1 tsp cumin
1 tsp oregano
1/2 tsp pepper
1/4 tsp cayenne pepper
1 cup fat free sour cream or plain yogurt
1/2 cup milk (the recipe calls for whipping cream but who needs the extra calories?)

In pan saute' chicken, onion & garlic in oil. Add beans, broth, chiles & spices. Bring to boil & simmer. Cook uncovered for 30 minutes. Add sour cream and milk. Serve with jack cheese and green onion for garnish. Adam likes it with chips.
